' Application july 27, 1937, Serial No. 155,856

, 5 Claims.

This invention relates to new and useful improvements in wrapping machines, and it has for its special purpose to construct Va machine, which will perform the entire act of wrapping articles,

5 which are supported by, or mounted on sticks,

such as'candies, and the like.

The construction of our invention is to the effect, that when a stick is inserted in to an especially constructed holder, forming part of our said invention, and a suitable piece of paper is fed to the machine, the latter will wrap, or fold,

' said paper around the article to be wrapped, twisting said paper around the stick, or securing it to the latter, as well as disposing of the article after the aforesaid operation is completed.

It will be Aobvious that our said invention will constitute a great improvementl as to time and labor saving, as one operator will be able to 'attend to two machines at the same time, while a speed as high as would be consistent with safety, may be attained in connection with a steady run of the machines, thus assuring a great and constant output.

It is further to be' noted that this inventionwil1 constitute a great progress in the field of sanitation, as the wrapping performed by the device, for instance of candy, will prevent the latter. being touched by the hands of anybody.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings, forming part of this application, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a side elevational view of the central part of our invention, showing part of the frame work removed.

Figure 2 is a transverse sectional view, taken on the line 2-2 in Figure 1.

Figure 3 'is a front elevational view of our invention, showing it at a certain stage in its operation, with parts being shown in section.

Figure 4 ,is an enlarged detailtransverse sectional view, taken on the line 44 in Figure 3, during one stage of the operation of the machine.

y Figure 5 is a similar view, taken of the next stage in said operation.

Figure 6 is a detail sectional view, taken on the line 5-5 in Figure 4. t

Figure '7 is a detail top plan view of the -twisters of the machine, in an open position; while Figure 8 shows the same, when closed;

Figure 9 is an enlarged detail transverse sectional view of the central portion of said twisters, when these are in a closing movementr around the stick; and 1 Figure 10 is a detail view, showing specifically a construction, illustrated in the Figures 2 and' 3. 5 Referring more particularly to the drawings, the main features of our inventionmay be said y to be vembodied in the following, relatively cooperating elernents: A holder, or apparatus, indicated at I0 and adapted toreceive therein the 10 stick of a piece of candy fto'be wrapped a coneor funnnel-shaped collar, show at II; clawshaped members, indicated at I2 and forming part of a constantly rotating, tubular shaped body, shown at I3'; a pair of twisters I4, gear 15 operated, and adapted to wrap or twist a piece of paper 28 around the stick of the candy; a ring-shaped member I5 for the manipulation of the claws I2; and a cam and crank arrangement,

of which the cam I6 in connection with a forked 2 arm I1 forms part of the means for operating the holder I0, .while cams I8 in conjunctionl with spring-actuated studs I9 impart motion to the aforementioned ring member I5.

The actual operation of our device may be 25 said to be as follows: I

When the stick 20, to whichthe candy is secured, is inserted into the opening 2| of the holder I0, said stick will push a small connecting bar 22 upward, thereby closing a circuit in a builtin switch, the negative and positive poles of which are indicated by the numeral 'I2 in the Figures 2 and 3, and which switch, in turn, will start a motor, or other electrical means, and thus set the device in motion."v 35 A small spring-actuated steel ball 23, will hold the stick 20 in place, temporarily, after said stick is inserted into the opening 2|. The holder I0 is secured to an arm 24, which, in turn, is connected to a vertically operated bar-25. As the sticks 20 will vary in length for the different kinds of articles, or candies, to be wrapped, the arm 24 is adjustable'with respect to said bar 25, for instance, as indicated in Figure 1, by a telescoping arrangement 26, secured by a 5 set screw 21.

Thus, in the relative operations, a piece of wrapping paper 28, is automatically fed from a paperv roll 29, and automatically cut to the proper size, and placed above the funnel-shaped member 50 II;'the latter is secured to a plate 30, as may, especially, be seen in the Figures 1 and 2.

As the paper roll 29 and the cutter 46 may be of Iany approved make, they are merely indicated on the drawings. y. y u

The holder I0, which vis shown in Figure 1 at its highest point, will on its downward movement, caused by the force of gravity, and as soon as the cam-operated', fork-shaped arm I1 permits,

force the piece of candy 80 through the funnelshaped opening 3|, thereby causing the paper 28 to fold around said candy and form a wrapper therefor as has been partly illustrated in the Figure 9.

'I'he fork-shaped part of the arm I1v may be replaced, however, by a link-arm connection of the ordinary and well known make. The operation of said fork-shaped arm I1 is clearly illustrated in Figure 1 in connection with a cam I6 secured to an axle 13 to which latter is also secured a gear 36.

A block 32 to which the arm I1 is pivotally secured, as indicated by the numeral33, forms part of the frame work of the invention.

An axle 34 provided with gears 35, in mesh with the gears 36, has two smaller cams 31 secured thereto, so that said cams, at the moment the holder I is at its lowest position or point,

will start the upward movement of the two rods, or studs I9, which latter terminate at their lower ends in fork-shaped guiding members 38; small rollers 39, cooperating with the cams 31, are pivotally arranged on said fork-shaped members, as shown at 40.

The upper ends of said studs are slidably arranged in the outer and reduced portion 8l of the ring member .I5, which latter is provided with openings 4I, as may especiallyo be seen in.

the Figures 2 and 4.

Springs 42, the action of which is regulated by setscrews 43, provide support for the ring member I5. A number of small studs 44, integral with the latter and slidably arranged in the frame 45, as shown at 46, provide an additional guidance and rigidity for the ring member I in its up and downward movement.

The tubular formed member I3, which during the operation of the device is kept constantly rotating by means of a belt-drive 41, or by suitable gears, has ball-bearings 48 arranged at the top and bottom thereof, in order to secure a smooth run of said member during the operation.

A suitable number of claw-shaped members I 2-of which herein are shown two-are pivotally arranged on the outside of the rotating tubular -member I3, thereby, in asense, forming a part of the same, as may be seen, especially in the Figures 2, 4, 5 and 6. Studs or pivots 5I secured to the belt-drive member 41, and an extended ring-formed member 52 at the lower end of the l drum, serve, respectively, as axles for said claws.

While one end of the claw is provided with a cut-off cone-shaped roller 53, pivotally mounted thereon, ythe other end of said claw terminates in a'semi-circular at portion 54, symmetrical in shape to the inside of the rotating drum and projecting through the wall of the same by means of cut-out portions 55 therein. Normally, the

flat portions of the claws will, actuatedv by the 'towards the center. The semi-circular'. claw- I0, which now starts upon its upward movement Y again.

While the article to be Wrapped now is held by the claws I2 rotating with the drum, another f cam, similar to the one indicated at 31 (but not shown) arranged on the same'axle 34, in conjunction with a link-arm 58, turnably arranged on the pivot 59, starts to move the two halfparts 69 and 60 loi" the twister towards each other guided by two tracks 14, which may be seen in the Figures 2, '7, 8 and 9. This arrangement is best illustrated in Figure 7, where the arm 6I is shown secured to a gear 62 by screws, or studs 65. A cut-out oblong portion 64, in the arm 6I, in conjunction with a bolt 63 secured to the twister, provides the necessary sliding arrangement'. Another gear 66 in mesh with the gear 62 and provided thereon with an arm 61,

latter, operates thef. other half of the twister.

The gears 62 and 66 are pivotally secured to the frame, as shown at 68.

It will easily be understood how the camoperated link-arm 58 will force `the two halfparts of the twister towards each other.

Thus one-half part of theh twister 60 is formed with two reduced portions 15 and 11 of a triangular shape; .the reduced portion 15 repre` senting the upper half at the top of the part 60, while the reduced portion 11 represents the lower half ofthe part 60; said two parts terminating in a curved central portion 19. f

A similar arrangement is to be found in regard to the part 60', wherein, however, the reduced portions 16 and 18 are reversely arranged4 in said part 60 in order to permit during operation, that the portion 15 will slide above the portion 16, and the portion 11 below the portion 18. By this time the claws will release their hold upon the candy, leaving the same to be held by the twister. It mayhere be noted that the central portion 82 is curved similarly to the before mentioned part 19.

A second switch 69, shown in Figure l, and actuated by the vertical bar 25y upon the downward movement of the latter, will keep the device in motion after the circuit is broken upon the removal of the stick voi" the candy from the holder I0, when the latter -is at its lowest position. Said switch 69 will subsequently cause the bar 25 to move upward again until this bar with the holder I6 has reached its original or highest position. At such time the contact between the bar 25 and the switch 69 will be broken, as may be seen in Figure 1; thus completing one cycle of operation.

When the next stick of a'piece of candy is inserted into the holder I8, the motor again starts to operate the machine; the cam manipulating the'twister, or the two parts composing the latter, will at the beginning of the new down- Ward movement of the holder have completed its rotation, and the spring 10 fastened to the frame and the arm 6Il will snap the parts of the twister back to the open position shown in Figure 7. The candy held by the twister will drop through an opening in the frame, and by means of a chute 1I be removed from the machine.

unit, making it possible for one operator to feed two holders.

In 'this case the second switch 69 can be eliminated, as the built-in-switch of the second holder will take the place of the switch 69, for the second half of each cycle.

It is obvious that changes may be made in the construction, combination and arrangement of the parts within the scope of the appended claims, without departing from the spirit of the invention, and we do not, therefore, wish to limit ourselves toI the exact construction and arrangement shown and described herein.
